Abstract

The invention provides a hoisting and tower buckling integrated construction method for cable of arch bridge, and relates to the technical field of hoisting construction method of arch ribs of an archbridge. Two sets of tower frames of the same structure, that is, a main cable tower frame and a buckle cable tower frame, are integrated and systematically arranged, the arrangement of a buckle toweris reduced, so that the method is easier to adapt to; construction of arch bridges at places restricted by geographical conditions such as mountainous areas; the method reduces the input of cable system equipment and the engineering quantity of the cable arrangement, saves the engineering cost and shortens the construction period; the whole construction is monitoring the integrated tower frame, so that components can be more conveniently hoisted to the designated position, and then through cooperation of a buckle cable system, a guy cable system and the measurement, accurately adjusting and positioning the axis and the elevation are realized.

Description

technical field [0001] The invention relates to the technical field of hoisting construction methods for arch ribs of arch bridges, in particular to an integrated construction method of hoisting tower buckles with cables for arch bridges. Background technique [0002] The concrete-filled steel tube arch bridge is a new technology developed in bridge construction in my country in recent years. It has light weight, high strength, and strong deformation resistance. It is an ideal structural form of long-span arch bridges. Concrete-filled steel tube arch bridge is a composite structural material formed by filling concrete into steel tubes. Experiments have proved that this material has the advantages of high strength, good plasticity and toughness, fatigue resistance, impact resistance, etc., so it is widely used in bridges and other projects. There are mainly stent method, cantilever method and other methods. [0003] With the accumulation of experience and the development of ...
